(2) For optimum voltage accuracy the `Remote Sense (+)' and `Remote Sense (-)' pins must be connected to +Vout and -V out respectively. (3) The Remote On/Off control (pin 1) has an internal pull-up. If pin 1 is left open the PT4500 will operate when input power is applied. A small lowleakage (<100nA) MOSFET must be used to control this input. The open-circuit voltage is less than 10V. See application notes for further information. (4) External output capacitance is not required for proper operation. Capacitamce may be added to improve the response to load transients. The maximum total capacitance (including the load circuit) must not exceed 220F, and the combined ESR of must not be less than 100m. (5) See Safe Operating Area curves or contact the factory for the appropriate derating. (6) During solder reflow of SMD package version do not elevate the module case, pins, or internal component temperatures above a peak of 215C. For further guidance refer to the application note, "Reflow Soldering Requirements for Plug-in Power Surface Mount Products," (SLTA051). (7) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.

This protects both the module and upstream source against load faults. Applying a load, in excess of the current limit threshold, will simply cause the output voltage to drop. The output current remains limited, but continues to flow in the fault. The drop in output voltage will vary according to the severity of the fault. Applying a short circuit to the output will result in an output voltage of zero, and the fault current will be limited to a value slightly higher than the current limit threshold. Upon the removal of the load fault, the output voltage of the module will fully recover to its normal regulated output voltage. Primary-Secondary Isolation The PT4500 and PT4520 series of DC/DC converters incorporate electrical isolation between the input terminals (primary) and the output terminals (secondary). All converters are production tested to a withstand voltage of 1500VDC. The isolation complies with UL60950 and EN60950, and the requirements for operational isolation. This allows the converter to be configured for either a positive or negative input voltage source. Output Voltage Adjustment The output voltage is typcially adjustable over a range of 10% of nominal. Consult the separate application note, "Ajusting the Output Voltage of the PT4500/PT4520 Series of Isolated DC/DC Converters." Turn-On Time The typical turn-on time is typically 35 milliseconds at Vin =48V. This is from application of input power, or the removal of a low-voltage signal from the Remote On/Off (pin 1). This includes about about 5-10ms of delay time before the output voltage begins to rise. Turn-on time will vary slightly with input voltage, output load, and the total amount of capacitance connected to the output. Input Current Limiting The converter is not internally fused. For safety and overall system protection, the maximum input current to the converter must be limited. Active or passive current limiting can be used. Passive current limiting can be a fast acting fuse. A 125-V fuse, rated no more than 5A, is recommended. Active current limiting can be implemented with a current limited "Hot-Swap" controller. Thermal Considerations Airflow may be necessary to ensure that the module can supply the desired load current in environments with elevated ambient temperatures. The required airflow rate may be determined from the Safe Operating Area (SOA) thermal derating curves. These are provided in the "Typical Characteristics" section of the converter specifications. Remote On/Off Function The output voltage from the converter can be turned off from the primary side using the Remote On/Off control (pin 1). Consult the separate application note, "Using the Remote On/Off Function on the PT4500/PT4520 Series of Isolated DC/DC Converters." Under-Voltage Lock-Out The Under-Voltage Lock-Out (UVLO) circuit prevents operation of the converter whenever the input voltage to the module is insufficient to maintain output regulation. Below the UVLO threshold the module is off and the Remote On/Off control (pin 1) is inoperative. Table 1-2 gives the applicable UVLO thresholds. Table 1-2; UVLO Thresholds Series UVLO Threshold Vin Range PT4520 PT4500 36 - 75V 18 - 40V 31V Typical 16.5V Typical For technical support and more information, see inside back cover or visit www.ti.com Not Recommended For New Designs Application Notes PT4500/4520 Series Adjusting the Output Voltage of the PT4500/ PT4520 Series of Isolated DC/DC Converters The factory pre-set output voltage of TI's PT4500 and PT4520 series of isolated DC/DC converters may be adjusted within a nominal 10% range. Adjustment is made from the secondary side of the regulator1 with a single external resistor. For the input voltage range specified in the data sheet Table 2-1 gives the allowable adjustment range for each model, as Vo (min) and Vo (max). 4. Never connect capacitors to Vo adjust. Any capacitance added to the Vo adjust control pin will affect the stability of the converter. The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulas. Adjust Up: An increase in the output voltage is obtained by adding a resistor, R2 between Vo Adjust (pin 12), and -Vout (pin 7, 8). Adjust Down: Add a resistor (R1), between Vo Adjust (pin 12), and +Vout (pin 9, 10).

The maximum rated output power for this series is 20W. An increase in the output voltage may therefore require a corresponding reduction in the maximum output current (see Table 2-1). The revised maximum output current must be determined as follows. 20 Io(max) = A, Va = Where Vo Va Vr Ko Rs Refer to Figure 2-1 and Table 2-2 for both the placement and value of the required resistor, (R1) or R2.

This function may be used in applications that require battery conservation, power-up/ shutdown sequencing, and/or to coordinate the power-up of the regulator for active in-rush current control. (See the related application note, SLTA021). This function is provided by the Remote On/Off control, pin1. If pin 1 is left open-circuit, the converter provides a regulated output whenever a valid source voltage3 is applied between +Vin(pin 4, 5), and -Vin (pin 2, 3). Connecting pin 1 to pin 2, or applying a low-level signal to pin 1 (with respect to -Vin), 1 will disable the regulator output 5. Table 3-1 provides details of the interface requirements for the Remote On/Off pin. Figure 3-1 shows how a discrete MOSFET (Q1), may be referenced to the negative input voltage rail and used with this control input. Table 3-1 Inhibit Control Requirements 1 Parameter Min Max Enable (VIH) 2.5V (Open Circuit) 4 Disable (VIL) -0.3V 0.8V Notes: 1.

Using the circuit of Figure 3-1, Figure 3-2 shows the output voltage and input current waveforms of a PT4521 after Q1 is turned off. The turn off of Q 1 corresponds to the drop in Q1 Vgs voltage. The waveforms were measured with a 48Vdc input voltage, and 2.75-A resistive load. Figure 3-2 2. The on/off control internal circuitry is a high impedance 10A current source. The open-circuit voltage may be as high as 8.3Vdc. Vout (2V/Div) 3. The PT4500/20 series incorporates an "Under-Voltage Lockout" (UVLO) function. The UVLO prevents operation of the converter when there is sufficient input voltage to support a regulated output. Below the UVLO threshold voltage, there is no output from the module and the Remote On/Off control is inoperative. Iin (0.2A/Div) 4. The Remote On/Off input of the PT4500/20 series must be controlled with a low-leakage (<100nA) opendrain MOSFET. Do not use a pull-up resistor. 5. When the converter output is disabled, the current drawn from the input supply is typically reduced to 8mA (16mA maximum). Q1 Vgs (10V/Div) HORIZ. SCALE: 5ms/Div 6. Keep the on/off transition to less than 1ms. This prevents erratic operation of the ISR, whereby the output voltage may drift un-regulated between 0V and the rated output during power-up.

TI bases its knowledge and belief on information provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties. TI has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals. TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release. In no event shall TI's liability arising out of such information exceed the total purchase price of the TI part(s) at issue in this document sold by TI to Customer on an annual basis. Addendum-Page 2 IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
